I am having a lot of trouble keeping my (just filled the other day) pool chlorinated, and I realize that it is due to the lack of CYA. I have NONE!
I have added Muriatic Acid by crushing it in some water in a bucket & then pouring the fine material into my skimmer. Am I diluting this too much by doing so? I just read in another thread that there are suggestions to hang the Muriatic Acid in some panty hose over the side of the pool in front of the outward flow of the pump, is this something that can stay in the pool while people are swimming in it until it dissolves, or should it be removed then replaced?
My pool gets a lot of direct sunlight during the day, so I'm sure that is good reason why my chlorine is getting eaten. I've went from 2 to .5 since this morning.
Here are the results I've just taken.
CH 700 - Woah, much higher than my kit says is acceptable, but not sure if it matters because I have a vinyl AG pool?
CYA - non existent, still saw that lovely black dot after completely filling tube.
I'm attempting BBB, if it matters.
Thank you to anyone who replies, I feel like a complete noob here & I'm very confused by all the information!
